This invention relates to a nozzle structure designed with particular reference to the requirements of service in vegetable and fruit spraying and similar work although not limited thereto.

In the spraying of vegetables and the like there is a particular needfor a suitable strainer construction to be incorporated in the spray nozzle due to the fact that the discharge ori-- fice of a spray nozzle adapted for this class of service is necessarily quite small. Spray nozzles must, to be serviceable for this use, be of a relatively small size so that to prevent the clogging of the discharge orifice therein there must be a maximum straining or filtration of the material before it reaches the discharge orifice to prevent the clogging thereof by arsenate of lead or lime contained in the spray solutions.

An object of the invention therefore is to provide the casting forming the spray nozzle with a tubular strainer running from end to end of the casting and to provide the i Fig. 2 is a sectional view taken on line 2-2, Figure 1.

The numeral 1 designates generally the casting for the spray nozzle whichas stated, 7 must be of rather small construction. This casting is provided with an inlet 2 in the side thereof screw threaded as at? to receive a suitable conduit for conveying spraying solution; One end of the casting is closedas shown at 4 while the adjacent end is open and provided with screw threads 5.

larged recesses 7 and 7 at 'diametricallyopposite points as shown, whilethe end thereof is constricted as at 8 to furnish a bearing for the amma. a

At the adjacent end of thenozzle Iprov-ide what I term as a plug 10 having a-s'eries-of tangentially disposed apertures 11. This plughas a cut out portion as at.12 in order toforni a shoulder to support the end o'fithe strainer.) r I .A cap havlng a dischar'georlfice is indicated'by reference numeral l3. Thiscap is Y spaced from the plug by the packing 1% 'to form a little eddy'chamber. The cap and plug with the interposed packing are isecur'ed -to the open ended nozzle by 'means'of a clamping r ng-'15'having aneXtension-l6 engaging the cap and screw threaded as at 17 'with'the casting sothat. .pre ssuremay be ustably exertedon'the packing ring. 7 1 I From the foregoing it will beseen that the 'spraying'solution entering the inlet at the side ofthe casting is distributed entirely within the confines of'the castingaround.

A i spray nozzle of the character described comprising a body casting having a lateral inlet and an elongated body portion, a tubular strainer located within the elongated bodyof the casting and extending from substantially end to end thereof and spaced from the casting to permit spraying solution to contactwith substantially all portions of the strainer, a cap having a discharge orifice located in alignment with the strainer and angularly disposed with respect to the inlet, a plug located within the confines of the body and having a portion interiorly engaging the strainer to center and maintain it in position 0 Z and a clamp engaging the nozzle cap and the casting to maintain the cap in position.

2. A spray nozzle of the character described comprising an elongated body portion hav- 5 ing a lateral inlet, a strainer located within the body portion and substantially coextensive therewith, said casting having one closed end against which one end of the strainer abuts, said strainer being spaced from the wallsof the body to permit thesolution to engage substantially all portions of the strainer, a plug located within the body and engaging the adjacent end of the strainer to maintain it in position, said plug having orifices therein, a spray cap having a dischar e orifice and a packing interposed between the plug and the cap to form a chamber therebetween and a ring engaging the cap and adjustably secured to the casting to maintain the cap and plug in position.

3. A nozzle structure for spraying solutions for treating vegetation and the like comprising an integral casting having a lateral inlet intermediate its ends adapted to V be attached to a source of supply for the solution and having one end closed, a tubular strainer of cylindrical formation located within the body of the casting and substantially coextensive therewith and slightly so spaced from the interior surface thereof,

said casting having, at its closed end, a circumferentially extending shoulder against which the end of the strainer frictionally fits to center the same, a plug engaging the adjacent end of the strainer to maintain the same in position, said plug being provided with obliquely extending discharge openings, a spray cap, and means for detachably securing said spray cap and plug in position relative to the casting.
